Disa's HPSA Tech Gets NRC License in Six Months for Uranium Mine Remediation
Disa Technologies, a growing player in environmental conservation, has received a significant regulatory milestone with the Nuclear Regulatory Commission (NRC) granting a license for its High-Pressure Slurry Ablation (HPSA) Technology in just six months. This innovative method offers a more efficient mechanical approach to processing and separating contaminated materials, avoiding additional chemical introduction into the environment.
The western United States faces a substantial environmental and public health challenge with an estimated 15,000 abandoned uranium mines. Many of these are located on or near tribal lands, including the Navajo Nation. HPSA Technology provides a solution, validated by the U.S. Environmental Protection Agency (EPA), the Navajo Nation EPA, and Idaho National Laboratory. The technology creates two distinct output streams: a coarse, sand-like material that potentially meets standards for reintegration into remediation sites, and concentrated fines containing uranium, thorium, and other metals for proper disposal or recovery. The NRC's approval process included a comprehensive environmental review that resulted in a finding of no significant impact, providing confidence in the technology's safe deployment. Compared to traditional remediation methods, HPSA offers advantages such as reduced volume requiring disposal, avoidance of additional chemical contaminants, and more efficient separation.
The NRC license establishes a phased approach to implementing HPSA Technology, starting with a demonstration phase involving up to 12,000 tons of waste over 180 days, followed by potential expansion to unlimited quantities of source material processing. Effective remediation of abandoned uranium mines offers potential benefits beyond environmental protection, including restoration of land for productive use, reduction of public health risks, and employment opportunities. Disa Technologies continues to play a crucial role in environmental conservation, particularly through innovative methods for decontamination and processing of contaminated materials.
